hello i got problem with chest 1 got a bit shape and no other one not its like i train on chest only!! geneticts or training what is the problem and how i fix it??
pic attaches

the 2st is a bit older but u can see it started since i took it

I've had this problem too, and i think its a training problem. I know when i use the barbell, my dominant side is doing most of the work, and I needed to focus using my weaker side in order to balance it out. Dumbbells will definitely help with that.
